This fairytale begins with a king that has three girls. The king loved to walk in his garden, and he loved one particular apple tree so much that if anyone picked from it they would be "wished underground." Once day, the three girls picked from the tree because they did not think their father would ever wish that upon his own daughters. However, the girls were sunk underground. The king had men searching for his beloved princesses for a reward. Three huntsmen in particular were searching for the girls. The youngest, "Stupid Hans", was the only one able to stand up to the mannikin (earth mannikin). Therefore, the earth mannikin told Hans where the girls were. As he was saving the girls from the bottom of the well, Hans's two older brothers cut the rope before he could get up. Distraught, Hans found a flute at the bottom of the well, which he began to play. The gnomes responded to the music and saved Hans from the bottom of the well. The king ended up killing Hans's brothers, and he gave Hans the youngest daughter and glass shoes.
This fairytale could be used to teach faithfulness and loyalty (morality development).
This fairytale would also be great to use for cause and effect.
